stress hormones in urologic surgery

In 2007 the Nordic group came to the following unanimous conclusions: In general, hormonal treatment is not recommended, considering the poor immediate results and the possible long-term adverse effects on spermatogenesis. Thus, surgery is to be preferred. However, defective mini puberty inducing insufficient gonadotropin secretion is one of the most common causes of nonobstructive azoospermia in men suffering from congenital isolated unilateral or bilateral cryptorchidism. The extent of alteration in the unilateral undescended testis correlate with the contralateral descended testis, indicating that unilateral cryptorchidism is a bilateral disease...

BACKGROUND: Treatments to stimulate spermatogenesis and antioxidant food supplements are often offered to infertile patients either before sperm extraction surgery to improve results, or as part of medically assisted reproduction or spontaneous fertility to increase the likelihood of a live birth. METHODS: A bibliographic search limited to English-language literature on men published before 5/2023 was carried out, including clinical trials, literature reviews and meta-analyses on spermatogenesis-stimulating molecules and antioxidant treatments...

Obesity has received considerable attention in general medicine and nephrology over the last few years. This condition increases the risk of metabolic syndrome, diabetes mellitus, hypertension, and dyslipidemia, which are the main risk factors for developing chronic kidney disease (CKD). Kidney damage caused by obesity can be explained by many mechanisms, such as sympathetic nervous and renin-angiotensin-aldosterone systems activation, mechanical stress, hormonal unbalance, as well as inflammatory cytokines production...

OBJECTIVES: Our study aimed to elucidate the possible relationship between endogenous circulating testosterone and the beginning and development of stress urinary incontinence (SUI) in postmenopausal women. PATIENTS AND METHODS: The clinical data of female patients with SUI who underwent surgery at our hospital from January 2014 to February 2023 and healthy female volunteers recruited during the same period were retrospectively analyzed according to age and body mass index (BMI)...

BACKGROUND: Although survival rates for newly diagnosed prostate cancer patients are very high, most of them will likely suffer significant treatment-related side effects, depression, or anxiety, affecting their quality of life. OBJECTIVE: The aim of this study was to examine the effects of a 6-mo online home-based physical, mental, and social support intervention, the Prostate Cancer Patient Empowerment Program (PC-PEP), on preventing psychological distress among men undergoing curative prostate cancer treatment...

Polypropylene (PPL) mesh is widely used in pelvic floor reconstructive surgery for prolapse and stress urinary incontinence. However, some women, particularly those treated using transvaginal PPL mesh placement for prolapse, experience intractable pain and mesh exposure or extrusion. Explanted tissue from patients with complications following transvaginal implantation of mesh is typified by a dense fibrous capsule with an immune cell-rich infiltrate, suggesting that the host immune response has a role in transvaginal PPL mesh complications through the separate contributions of the host (patient), the biological niche within which the material is implanted and biomaterial properties of the mesh...

OBJECTIVE: To develop a core outcome set (COS) applicable for effectiveness trials of all interventions for localised prostate cancer. Many treatments exist for localised prostate cancer, although it is unclear which offers the optimal therapeutic ratio; which is confounded by inconsistencies in the selection, definition, measurement and reporting of outcomes in clinical trials. PATIENTS, SUBJECTS AND METHODS: A list of 79 outcomes was derived from a systematic review of published localised prostate cancer effectiveness studies and semi-structured interviews with 15 patients with prostate cancer patients...

Stress incontinence is one of the major challenges in geriatric medicine. This is becoming more apparent in routine urology practice with the demographic changes in the population. A thorough diagnosis for a correct treatment of stress incontinence is as important in elderly women as it is in younger patients. This includes assessing the risk factors of incontinence and obesity, parturition, pelvic surgery and changes in hormone levels are risk factors usually found in elderly women. These are the main reasons why this patient group is most frequently affected...

INTRODUCTION: Surgical intervention and anesthesia procedure lead to a series of hormonal changes in the organism, which is mainly attributed to catecholamine response to stress. Surgical intervention is resulting in significant changes in neuroendocrine regulation, metabolism and physiological functions, as part of the overall response to stress. RESEARCH AIM: The aim of this study was to determine and evaluate the levels of hormones in patients undergoing transvesical prostatectomy under general or local anesthesia...

OBJECTIVE: The aim of this review was to assess the clinical utility of portable bladder ultrasound. CLINICAL NEED: TARGET POPULATION AND CONDITION Data from the National Population Health Survey indicate prevalence rates of urinary incontinence are 2.5% in women and 1.4 % in men in the general population. Prevalence of urinary incontinence is higher in women than men and prevalence increases with age. Identified risk factors for urinary incontinence include female gender, increasing age, urinary tract infections (UTI), poor mobility, dementia, smoking, obesity, consuming alcohol and caffeine beverages, physical activity, pregnancy, childbirth, forceps and vacuum-assisted births, episiotomy, abdominal resection for colorectal cancer, and hormone replacement therapy...

UNLABELLED: What's known on the subject? and What does the study add? Ovary hormone deficiency and the age-related changes in post-menopausal women are subjected to a number of urological dysfunctions, including overactive bladder syndrome. Green tea is a popular healthy drink worldwide and its extract catechin has strong anti-inflammatory and antioxidant properties. EGCG, the major type of catechin, is an antioxidant polyphenol flavonoid isolated from green tea. EGCG supplement could prevent ovariectomy-induced bladder dysfunction in a dose-related manner through its anti-oxidant, anti-fibrosis and anti-apoptosis effects...

INTRODUCTION: Hypovolemia and pain are direct stimulators of hormonal response to trauma. Thus, neuroendocrine, metabolic and inflammatory aspects of the injury are part of an overall "stress response". In particular, it manifests in patients undergoing surgical intervention. These reactions can occur with trauma, burns, severe infections and physical exertion. Metabolic and neuroendocrine response to surgical intervention depends on several factors, such as severity and duration of the surgical trauma, patient's age, type of anesthesia and surgical techniques...

Organ-sparing approaches are currently practiced in urology for many malignancies. Partial orchiectomy of germ cell tumors (GCT) provides potential benefits over radical surgery by reducing the need for androgen substitution, lessening psychological stress, and preserving fertility, with a durable cure rate. Furthermore, many testicular lesions detected clinically or by ultrasonography will be benign, in which case radical orchiectomy represents overtreatment. Partial orchiectomy for benign lesions allows preservation of endocrine and exocrine function, and reduced risk of local recurrence...

Although it is not possible to use medications on the anatomic features of incontinence, a better comprehension of the physiopathology of miction impairment can lead to pharmacological treatment of female urinary incontinence. However, analysis of the literature shows that few publications are methodologically satisfactory, nor are they comparable. In presence of stress urinary incontinence, vaginal hormone treatment must be provided if the patient presents vaginal atrophy with physical therapy or surgery planned...

PURPOSE: to observe the impact of obesity and other risk factors on the rate of failure in patients submitted to Burch's surgery for the treatment of urinary incontinence. METHODS: cases study of patients submitted to Burch's surgery, from 1992 to 2003. Patients were evaluated at the second post-surgery appointment (average 66 days) and after one-year follow-up, and classified in two groups: Continent and Non-continent. Variables analyzed were: age, parity, body mass index (BMI), menopause duration, duration of hormonal therapy, urodynamic evaluation, history of urinary tract infection, previous urinary incontinence surgery, diabetes, cystocele and uterine prolapse, time spent in hospital, necessity of self-probing, post-surgical spontaneous micturition, and surgical wound...

Estrogens are crucial for the proper functioning of genitourinary tract. Hypoestrogenism related to menopause could be linked to numerous disturbances of lower urinary tract. However, the results of most well designed clinical studies do not support use of estrogen or hormone replacement therapy for the treatment of genitourinary symptoms. According to evidence base medicine stress urinary incontinence, overactive bladder syndrome or pelvic organ prolapse are best treated by the surgery or non-hormonal drug therapy...

OBJECTIVES: To evaluate the feasibility, the efficacy and the innocuousness of suburethral transobturator support using multifilament polypropylene transobturator tape (TOT) inside out for stress urinary incontinence in women. MATERIALS AND METHODS: The study concerns 70 patients representing our team's first experience of this technique. The inclusion criterion was persistent SUI despite perineal rehabilitation. There were no exclusion criteria. Among the 70 patients, 22 (31%) presented with associated genital prolapse...

AIMS: Many parameters have been utilized to try to estimate severity of stress urinary incontinence (SUI). Valsalva leak point pressure (VLPP) measurements, have been proposed as a reliable means of gauging the severity of SUI during urodynamic studies (UDS). Certain, non-invasive, measures of incontinence severity have been proposed, but the correlation of these measures with VLPP is not known. In addition, the correlation of other important UDS measures and VLPP has not been evaluated...
